which graph most accurately represents the gas content and the composition of magma? rhyolite andesite basalt (1) rhyolite andesite basalt (3) rhyolite andesite basalt (2) rhyolite andesite basalt (4) 1 2 3 4
Answer
Explanation:
Step1: Recall gas - content in magmas
Rhyolite magma has the highest gas content, and basalt magma has the lowest gas content among rhyolite, andesite, and basalt magmas.
Step2: Analyze bar - graphs
In graph (1), the bar for rhyolite is the tallest (indicating highest gas content) and the bar for basalt is the shortest (indicating lowest gas content), which is consistent with the known gas - content relationships of these magmas.
